Logistics has long been recognized as the main effective tool for generating competitive advantages in trading enterprises, and therefore there is an acute problem in finding strategic guidelines for improving logistics activities through the lens of organizational and economic support of logistic activity of a trading enterprise. The article compares the main reference models for the analysis of logistics activities and found the most appropriate for use-SCOR model, which identified the main indicators for evaluating the performance of logistics activities. An algorithm for determining the level of efficiency and performance of logistic activity have been constructed. According to the results of the study, the level of organizational and economic support, perormance and efficiency of logistic activity of trade enterprises of Ukraine of the sample population have been determined.

Agility is the fundamental characteristic of a supply chain needed for survival in turbulent markets, where environmental forces create additional uncertainty resulting in higher risk in the supply chain management. In addition, agility helps providing the right product, at the right time to the consumer. The main goal of this research is therefore to promote supplier selection in pharmaceutical industry according to the formative basic factors. Moreover, this paper can configure its supply network to achieve the agile supply chain. The present article analyzes the supply part of supply chain based on SCOR model, used to assess agile supply chains by highlighting their specific characteristics and applicability in providing the active pharmaceutical ingredient (API). This methodology provides an analytical modeling; the model enables potential suppliers to be assessed against the multiple criteria using both quantitative and qualitative measures. In addition, for making priority of critical factors, TOPSIS algorithm has been used as a common technique of MADM model. Finally, several factors such as delivery speed, planning and reorder segmentation, trust development and material quantity adjustment are identified and prioritized as critical factors for being agile in supply of API.

Video compression has become a source of different research studies. It is necessary in order to address channel bandwidth limitations and growing video demand, including digital libraries and streaming media delivery via the Internet. A video is a number of frames captured by a camera while a scene is a series of consecutive frames captured from a specific narrative viewpoint. To compress a video, firstly, the intra frames are separated from inter frames using scene change detection methods. Then, block-based motion estimation algorithms are used to eliminate the temporal redundancy between successive frames. This paper describes some scene change detection methods for use on the uncompressed video to detect scene types such as cut, dissolve, wipe, etc. Absolute Frame Difference (AFD), Mean Absolute Frame Differences (MAFD), Mean Histogram Absolute Frame Difference (MHAFD), and Maximum Gradient Value (MGV) techniques are adaptively tested on different video types to identify accurate scene change in both low and high object motion scenes. Test results show that the proposed approach (MHAFD ) obtains a better accuracy, F1-SCOR measure of 100%, especially for cuts and gradual transitions (wipe) video types. Dissolve scene change is detected with a high precision of 100% (i. e., no false detection) with the (MAFD) detector. Besides, in terms of time complexity for analyzing all the video samples, the proposed method (MHAFD) provides the best result compared to the selected detectors.

Background: Transient tachypnea of the newborn (TTN) is a common cause of respiratory distress in the neonatal period. There are few data regarding the pharmacotherapy for the management of TTN. Previous studies documented the therapeutic role for the beta2 agonists in TTN by accelerating the clearance of excessive fluid from the alveolar space. The aim of present study was to assess the effect of salbutamol on major clinical outcomes including duration of oxygen therapy and improvement of respiratory symptoms. Methods: This double blinded randomized clinical trial was conducted in 2014 in three urban tertiary care centers of Babol, North of Iran. Patients were assigned to receive either inhalational salbutamol (35 patients) or placebo (35 patients), and clinical outcomes were compared Before and after treatment in interval of 30 minutes, one, four and six hours from the beginning of the study. Results: There was no significant difference between the clinical findings of salbutamol and placebo group before and 24 hours after the initiation of the study. After the exclusion of the neonates with retraction silverman anderson SCOR < 2, in salbutamol group the mean values of primary outcomes including; duration of oxygen therapy (P = 0. 04) and hospitalization (P = 0. 006) as well as initiation of enteral feeding (P = 0. 013) were significantly lower than in placebo group. Conclusions: Inhaled salbutamol resulted in shorter duration of respiratory support and hospitalization and earlier initiation of enteral feeding in TTN patients with moderate to severe respiratory symptoms. Further RCT studies with a larger study population and higher retraction SCORe are suggested to achieve valid data in the management of TTN.
